Drinking water in Iffwil, Scheunen
3 supply zones — values can differ depending on the district. Below is the zone with the most documented parameters, the others collapsed underneath. To determine the exact match, look up the postcode.
How to read the share of the parametric value
Several samples per year: for chemical parameters the mean value is given, for microbiological ones the highest measured value. There the parametric value is zero — a single finding would disappear in the average, and it is precisely that finding which is the information. Which reference applies is stated in the last column of the table.
WVS Zone Mitte
Gemeindeverband Wasserversorgung SaurenhornAssigned via the water supplier — the exact supply zone boundary within the postcode is not yet linked.
These values are more than a year old. The most recent analysis the water supplier has published for this zone dates from 31/12/2024. We have no newer values — which is why we show the latest available ones rather than none at all. They say nothing about how the water has changed since then.

Annual means and medians are not individual measured values, but the parametric values apply per sample. If a mean lies above it, at least one individual sample was above it — the mean does not say how many, or by how much. That is why this is not reported here as an exceedance of the parametric value. What counts remains the water supplier's publication, which each row links to.

Frequently asked questions about drinking water in Iffwil, Scheunen
- How hard is the water in Iffwil, Scheunen?
- Gemeindeverband Wasserversorgung Saurenhorn publishes a total hardness of 23.5 °fH for the supply zone WVS Zone Mitte — that corresponds to 13.2 °dH. The hardness range is a classification under the German Detergents and Cleaning Products Act (soft below 8,4 °dH, medium 8,4 to 14 °dH, hard above that) and not a quality verdict — it indicates how much calcium and magnesium is dissolved in the water. Basis: 2024, retrieved on 07/08/2026.
- How much nitrate is in the drinking water in Iffwil, Scheunen?
- Gemeindeverband Wasserversorgung Saurenhorn publishes a nitrate value of 11.5 mg/l for the supply zone WVS Zone Mitte. The statutory parametric value is 40 mg/l; the measured value represents 29 % of the parametric value. Basis: 2024, retrieved on 07/08/2026.
- Who supplies the drinking water in Iffwil, Scheunen?
- Gemeindeverband Wasserversorgung Saurenhorn. The values shown here come from the supply zone WVS Zone Mitte and apply to the water the supplier delivers. What happens between the building connection and the tap — in old lead pipes, for example — is not covered by these analyses; information on that is provided by owners, the health authority or an examination by an accredited laboratory.
